I think that the .png is found. strace shows a very large number of
"Segmentation fault" errors. The first ones of a long list scattered
across the log are:

The first path is a directory and does exist. The second refers to an
existing file.

Could be, but I've not found obvious indications in the output of strace.

Does it work as expected for you?
